So, if solar variability can influence stratosphere temperatures, for example by
affecting ozone amounts differentially between equator and poles, then there you have it.
The cause appears not to be raw solar power output (TSI) which varies too little but instead, the precise mix of particles and wavelengths from the sun which vary more greatly and
affect ozone amounts above the tropopause.

The
amount of wave energy that moves up from the troposphere into the lower stratosphere (roughly 17 to 30 km altitude) significantly
affects the temperature, and therefore the
ozone depletion, at these altitudes, where the bulk of the
ozone layer is located.
For the runs with different emission and «climate» years, e.g. Em2000Cl1850, emissions of aerosol and
ozone precursors are set to 2000, methane
amounts for chemistry are set to 2000, but
ozone and methane at 2000 do not
affect the radiation (i.e. radiation sees 1850 «climate» conditions for everything but aerosols).
The IPCC (2001) report also documents the geographical variability of various aerosols,
ozone, black carbon, etc. that
affect the
amount of radiation available to enter the world ocean.»
